Unlike the GMail storage increase, Google Gulp is one of the first big April Fools jokes floating around the internet this year:

"At Google our mission is to organize the world's information and make it useful and accessible to our users. But any piece of information's usefulness derives, to a depressing degree, from the cognitive ability of the user who's using it. That's why we're pleased to announce Google Gulp (BETA) with Auto-Drink (LIMITED RELEASE), a line of "smart drinks" designed to maximize your surfing efficiency by making you more intelligent, and less thirsty."
